Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it. Bump PORTREVISION on their dependent
ports except the ones that depend on these:
audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt
In these cases the same trick as in the recent gettext update is used.

Convert graphics/sdl_gfx to USES=libtool. Also set USE_AUTOTOOLS because
upstream forgot to regenerate the build scripts. This makes the build use
the correct version information and causes a library version bump. Use
this opportunity to use USES=libtool instead of USES=libtool:oldver.
Bump PORTREVISION on all dependent ports and convert them to USES=libtool
where needed. Also use USES=(gmake, pathfix, tar) and new LIB_DEPENDS
syntax here and there.

- Use dirrmtry for locale directories.

- Staging.

According to the Porter's Handbook (5.12.2.3.) default options must be added to
OPTIONS_DEFINE. This policy has been implemented only recently that's why we
have many ports violating this policy.
This patch adds the default options specified in the Porter's Handbook to
OPTIONS_DEFINE where they are being used. Ports maintained by
gnome@FreeBSD.org, kde@FreeBSD.org and x11@FreeBSD.org have been excluded.

The original developer of xblast seems to have vanished years ago.
But now there appears to be active development, again, by a group
that has gathered patches from different sources and started to add
a number of new features.
Upgrade to xblast version 2.9.22.
